Hello, I have a few TAD 4001 compression drivers and bought new replacement diaphragms. Does anyone have a procedure for replacing? One main question is the silver square spacers between the diaphragm and housing. Some of mine have two, one stacked on top of each other, and one has only one. Which is correct? The new diaphragms have new spacers on them. Other information like alignment, screw torque, and first testing techniques would be great. Anything similar for a JBL 375 or 2440 will also help.
Any help is greatly appreciated.
Kind Regards
